Spatial and spectral information are combined and it is shown that single filaments in broad ridge (Al,In)GaN laser diodes (LDs) are phase-locked and form supermodes. Stable in-phase coupling of the single emitters or filaments over a wide current range is achieved in order to produce a stable laser beam for high power applications.
